• Abstract:

  The recent detection of binary neutron star (NSs) mergers opened the possibility to study their internal structure and equations of state of matter at supranuclear densities through the gravitational waves emitted during their coalescence. On the other hand, compact stars may accumulate a sizable amount of dark matter (DM) in their interior. Recent studies have shown that DM is able to significantly impact hadronic matter properties in the stellar interior. However, this seems to be an oversimplifying assumption, as in the core of compact stars matter could go through a phase transition from nuclear matter to a plasma of strongly interacting quarks, dubbed hybrid stars. Thus, the present PhD project is focused on a study of the impact of DM on the properties of hybrid stars, their evolution, stability against radial and non-radial oscillations as well as observational signals of the presence of quark-gluon plasma in the stellar core.
